Color Manager is a program for recoloring and manipulating existing icon packs, wallpapers and themes. The program is designed for NovaOS and is currently in early development. The first release will be late August 2023. In the meantime, this repository will act as a preview.

Instanty recolor artwork such as wallpapers.

Operation	Result
Original
Monochrome: (0.6, 0.54, 0.5)
Multichrome: dracula.json

To increase the perceived quality of multichromatic recolorings of pngs/jpgs, simply increase the number of colors in the palette you provide, e.g. populate it with slight variations of the existing colors, or alternatively decrease the number of colors in your original image. Svg recolorings will always be perfect.

GUI Demo:

Note: If you publish anything that was generated using this program, make sure to credit the original creator and this repository.

Roadmap

Basic framework for manipulating icon packs.
Grayscale, monochromatic and multichromatic recoloring functions.
Command-line interface.
Graphical user interface based on the GTK framework.
Python pip package.
Full support for pngs and jpgs.
Basic framework for manipulating GTK, Cinnamon and Metacity themes.
Intelligent color inversion function.
Function for adding basic geometry to the backgrounds of icons.
GNU/Linux binary.

Features

Currently, two types of recoloring operations are supported:

Type	Result	Speed	Supports
Monochrome	A monochromatic variant, colored by appropriate shades of the provided base color.	~5000 svgs/sec	svg, png, jpg
Multichrome	A multichromatic variant, where all colors are replaced by their nearest perceived equivalent that adheres to the provided color palette.	~100 svgs/sec	svg, png, jpg

Speeds were recorded with an Intel i7-4770K CPU. Any asset can serve as the base for any color palette or base color.

Using the Program

Either import utils into your own script and call the recoloring functions, e.g.:

from color_manager import utils

src     = "test_pack"
name    = "my_pack"
dest    = "~/Downloads"
hsl     = (0.5, 0.5, 0.5) # = rc.norm_hsl(180, 50, 50)
palette = "palettes/dracula.json"

utils.recolor(src, dest, name, hsl) # hsl or palette.

Or launch the GUI by running python3 color_manager/gui.py in a terminal from the project's root directory. The GUI will adopt your active theme. Dependencies: colormath, tqdm and pillow. For the GUI, pygobject (GTK bindings) must also be installed.

Requests

Until the release of Color Manager, I will be taking requests for icon packs and recolorings. Simply submit a feature request here on the repository containing the following:

The name of an open-source icon pack that will serve as the base look.
For a monochromatic variant, a single hexadecimal value representing a color.
For particular color palettes, a list of hexadecimal values or the name of a popular palette.

Please star the repository or consider donating, and I will upload your requested variant. Also consider showing the creators of the original artworks some love.
